Vector w is in the subspace spanned by {V₁, V₂, V3} because w is a linear combination of V₁, V₂, and V3. 1¹ B. Vector w is not in the subspace spanned by {V₁, V₂, V3) because the equation x₁v₁ + X₂V₂ + X3 V3 = w has no solution which can be seen because an echelon form of the augmented matrix of the system has a row of the form [0... 0 b] with b * 0. =W C. Vector w is not in the subspace Span{V₁, V₂, V3} because the rightmost column of the augmented matrix of the system X₁ V₁ + x₂ V₂ + x3 V3 = is not a pivot column. D. Vector w is in the subspace spanned by {V₁, V2, V3} because the subspace generated by V₁, V₂, and v3 is R³.

Is w in the subspace spanned by {V₁, V₂, V3}? Why?
1.
O A. Vector w is in the subspace spanned by {V₁, V₂, V3} because w is a linear combination of V₁, V₂, and V3.
